The Alpha Leonis system was an inhabited star system. Regulus was the primary of the system. Two planets were known to support life: Regulus III and Regulus V. Notable forms of life in this system included the eel-birds of Regulus V and the Regulan bloodworms. (TNG: "The Vengeance Factor"; Star Trek VI: The Undiscovered Country, production art; TOS: "Amok Time"; ENT: "Two Days and Two Nights") The system was located three hundred light years from the Bajoran system. (DS9: "Fascination")

In 2154, a Vulcan High Command attack fleet massed in this system in preparation for an abortive preemptive strike against the Andorians. Regulus was the closest accessible star known to be outside the maximum range of Andorian Imperial Guard listening posts. (ENT: "Kir'Shara")

A century later, in 2254, Christopher Pike considered retiring and going into business on Regulus or on the Orion colony. (TOS: "The Cage", "The Menagerie, Part I")

The location of Regulus in the Milky Way Galaxy was depicted on a Federation star chart of the explored galaxy in 2293. (Star Trek VI: The Undiscovered Country, production art)

In 2366, this system was in need of medical supplies, which were transported there by the USS Enterprise-D. (TNG: "The Vengeance Factor")

Background information

The association between the Alpha Leonis system mentioned in "The Vengeance Factor" and the Regulus star and planets is based on reference material and the real world association. According to Star Trek Maps (pg. 29), The Worlds of the Federation (pg. 130) and Startrek.com, Alpha Leonis was the same system as Regulus. In the real world Alpha Leonis is the Bayer classification name for Regulus. [1]

In the "The Explored Galaxy" star chart, Regulus was located between the Tholian Assembly and Romulus. Both were identified in DS9: "Call to Arms" as Alpha Quadrant powers.

According to the Star Trek: Star Charts (pgs. 56,61,62), the Regulus (also known as Alpha Leonis) system was located in the Beta Quadrant. It was a trinary star system. Regulus A was a B-class star with a magnitude of +1, which was a hundred times brighter than Sol. Regulus B was a M-class star. Regulus C was a K-class star. In 2152, this system was in non-aligned space. By 2378, the system had been incorporated into Federation space, and was a destination on the major space lanes.

Apocrypha

According to the novelization of the episode TOS: "The Man Trap", in Star Trek 1, the planet M-113 was the eight planet in the system, Regulus VIII.
